c# - 内部错误 : Item has already been added. 字典中的键: 'tmp' 正在添加的键: 'tmp'

Question

在过去的几年里，我一直在使用 Cruise Control .NET 持续集成服务器，它运行良好。最近，我在启动 WebDashboard 后开始收到此错误。有人对如何解决此错误有任何建议吗？我是不是在 ccnet.cong 中出错了？ TIA。

INTERNAL ERROR: Item has already been added. Key in dictionary: 'tmp' Key being added: 'tmp'

更新:这是我正在处理的代码——“ Action (请求)；”是 CruiseServer.cs 第 1512 行:

    /// <summary>
    /// Encapsulates the code to process a request.
    /// </summary>
    /// <param name="request"></param>
    /// <param name="permission"></param>
    /// <param name="eventType"></param>
    /// <param name="action"></param>
    /// <returns></returns>
    private Response RunServerRequest(ServerRequest request,
        SecurityPermission? permission,
        SecurityEvent? eventType,
        Action<ServerRequest> action)
    {
        Response response = new Response(request);
        try
        {
            // Validate the request and check the security token
            ValidateRequest(request);
            if (permission.HasValue)
            {
                CheckSecurity(request.SessionToken,
                    null,
                    permission.Value,
                    eventType);
            }

            // Perform the actual action
            action(request);
            response.Result = ResponseResult.Success;
        }
        catch (Exception error)
        {
            // Security exceptions have already been logged, just need to log any other exception
            if (!(error is SecurityException))
            {
                Log.Warning(error);
            }

            // Tell the caller the request failed and include the error message (but not the stack trace!)
            response.Result = ResponseResult.Failure;
            response.ErrorMessages.Add(
                new ErrorMessage(
                    error.Message,
                    error.GetType().Name));
        }
        return response;
    }

这是它最终要去的功能，然后我进入“data = integrationQueueManager ...”:

    /// <summary>
    /// Gets information about the last build status, current activity and project name.
    /// for all projects on a cruise server
    /// </summary>
    public virtual ProjectStatusResponse GetProjectStatus(ServerRequest request)
    {
        ProjectStatus[] data = null;
        ProjectStatusResponse response = new ProjectStatusResponse(RunServerRequest(request,
            null,
            null,
            delegate
                {
                data = integrationQueueManager.GetProjectStatuses();
                if (request.SessionToken != SecurityOverride.SessionIdentifier)
                {
                    data = this.FilterProjects(request.SessionToken, data);
                }
            }));
        if (data != null) response.Projects.AddRange(data);
        return response;
    }

接下来我进入“projectStatusList.Add...”:

    /// <summary>
    /// Gets the project statuses.  
    /// </summary>
    /// <returns></returns>
    /// <remarks></remarks>
    public ProjectStatus[] GetProjectStatuses()
    {
        ArrayList projectStatusList = new ArrayList();
        foreach (IProjectIntegrator integrator in projectIntegrators)
        {
            IProject project = integrator.Project;
            projectStatusList.Add(project.CreateProjectStatus(integrator));
        }
        return (ProjectStatus[]) projectStatusList.ToArray(typeof (ProjectStatus));
    }

最后，应用程序在“var lastIntegration = this.LastIntegration;”处抛出异常。在这个函数中:

    /// <summary>
    /// Creates the project status. 
    /// </summary>
    /// <param name="integrator">The integrator.</param>
    /// <returns></returns>
    /// <remarks></remarks>
    public ProjectStatus CreateProjectStatus(IProjectIntegrator integrator)
    {
        var lastIntegration = this.LastIntegration;
        ProjectStatus status = new ProjectStatus(
            this.Name,
            this.Category,
            this.CurrentActivity,
            lastIntegration.Status,
            integrator.State,
            this.WebURL,
            lastIntegration.StartTime,
            lastIntegration.Label,
            lastIntegration.LastSuccessfulIntegrationLabel,
            this.Triggers.NextBuild,
            this.CurrentBuildStage(),
            this.QueueName,
            this.QueuePriority,
            this.Parameters);
        status.Description = this.Description;
        status.Messages = this.messages.ToArray();
        status.ShowForceBuildButton = this.ShowForceBuildButton;
        status.ShowStartStopButton = this.ShowStartStopButton;
        return status;
    }

当我将鼠标光标悬停在“var lastIntegration = this.LastIntegration”上时，它显示“this.LastIntegration = 'this.LastIntegration' throw an exception of type 'System.ArgumentException'”。非常感谢您的反馈!

我在一个用户身上安装我的程序时遇到了同样的问题。原来问题出在Cygwin安装上，而不是我的程序。这是链接。
